Protect-O-Shield® Bearings


AMCO's Protect-O-Shield® bearing features an exclusive protective shield to enhance the life and protect its triple seals from damage, keeping you out of the shop and in the field.

  • ELIMINATES BLOWN SEALS


    • Too much pressure in your grease gun can easily blow out the seal in even the finest bearing. Protect-O-Shield® won't let this happen. It secures your seals in place.

  • NO MORE WRAP DAMAGE


    • Rice straw, wheat stubble, baling wire - all will tear up your bearings when wrapped around your harrow's axle. Keep it out with Protect-O-Shield® bearings. Wear guards and zerk guards are standard equipment.

    AMCO GUARANTEES PROTECT-O-SHIELD® BEARINGS FOR TWO FULL YEARS.



    Shock Absorber Gang Risers


    AMCO's challenge to rocks and stumps.

    Rocks and stumps in your fields are less of a problem with AMCO's Shock Absorber Gang Risers.

    AMCO's Shock Absorber Gang Risers allow the gang to move up and back when striking an obstacle while you plow.

    Couple the Shock Absorber Gang Riser with AMCO's Protect-O-Shield® bearings, and you have an unbeatable combination for work in rough terrain.

    AMCO's Shock Absorber Gang Riser and Protect-O-Shield® bearings will not move rocks and uproot stumps, but they will help prevent harrow damage.
